Globally, invasive species represent a major threat to native species. A new paper published this week in the open-access journal PLoS Biology shows that, for rivers and lakes, where these invasions occur is predicted by human activity; find an area where economic activity is high and, in nearby lakes and rivers, up to a quarter [...]

Ever since a forward-thinking trio of physicists identified the phenomenon known as self-organized criticality—a mechanism by which complexity arises in nature—scientists have been applying its concepts to everything from economics to avalanches. Now, researchers at the University of Michigan and the University of Toledo have shown that clusters of ant nests on a coffee farm [...]

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (21 December) in PLoS Pathogens. Researchers say this development is a step towards developing future methods of preventing the transmission of malaria. Malaria is caused by parasites whose lives [...]

New study shows that dogs can classify color photographs and transfer knowledge in computer tests. Like us, our canine friends are able to form abstract concepts. Friederike Range and colleagues from the University of Vienna in Austria have shown for the first time that dogs can classify complex color photographs and place them into categories [...]

The discovery of a giant fossilised claw.- from an ancient sea scorpion indicates that when alive it would have been about eight foot(two and a half meters) long, much taller than the average man.
